This invention relates to the art of fluid dispensers and particularly to a type of a dispenser adapted to be coin operated for dispensing gasoline and the like :for automobiles.

t is a primary object of the invention to provide a structure whereby upon deposit of a coin, a predetermined amount of fluid to be sold for the value of that coin automatically will be made available to be drained therefrom at the will of the purchaser all without aid or necessity of an attendant.

A primary object resides in the articular new association of elements where y a very and accurately measuring device is obtained.

A lprimary object also resides in the means provided to prevent dispensing more iiuid than that intended for the coin deposited.

Other important objects reside in the means for dumping the measuring tank in case of fire, means for easily adjusting the amounts of duid to be dispensed as the sales price of the duid may vary, and in means that may be manufactured and assembled at a very low cost.

These and other objects will become apparent in the following description of the invention made in reference to the accompanying drawings, in which Fig. 1 is a fragmentary side elevation of of a structure embodying our invention;

Fig. 2, a fragmentary front elevation;

Fig. 3, a'horizontal transverse section on the line 3 3 in Fig. 2;

Fig. 4, a det-ail in side elevation of a coin detector; and

Fig. 5, a detail in sect-ion on the line 5-5 in Fig. 4.

Like characters of reference indicate like parts throughout the several views in the drawings.

We mount a tank on a floor 11 carried by a frame 12 and lit to the tank, a supply pipe 13, an overflow pipe 14, a drain pipe 15, and a discharge pipe 16. In the drain pipe 15 is a valve 17 normally held closed by a combustible or fusible link, here shown as a cord 18, against the tending to open the valve.

Within the tank 10 are fixed a plurality of pull of a spring -19l vertically disposed guide rods 20, here, shown i as three in number. A oat 21 is slidingly carried on each rod 20, normally dropping to the bottom of the tank. Tubing of varying lengths, 22, 23, and 24 slipsover-the upper ends of the which bear against the upper cover l28 across the tank'lO. Y

A shaft 29 extends across the tank over the cover 28 in front of the guides 20 and carries individually rockably thereon the rock# ers 30, 31 and 32 each of which have a rearwardly extending arm in the path of vertical travel of the respective collar 25. In front of the shaft 29 and parallel thereto, but at a lower elevation, is a shaft 33, on which are rockably carried the bell cranks 34, 35 and 36. Links 37, 37, 37 interconnect the rockers and bell cranks whereby lifting that end of the rocker over the collar will lift the outer end of the bell crank. Cables 38, 39 and 40 extend downwardly respectively from the outer ends of the bell cranks 34, and 36 through tubes 41, 42 and 43 to the horizontally disposed arms of rockably mounted bell cranks 44, 45 and 46, the other arms of which project downwardly.

Behind the bell cranks 44, 45, 46 is a carriage made up from three spaced apart parallel arms 47, 48 and 49, rockably supported on the transverse shaft 50, ard a tie bar 51 across the rear ends of the arms. The forward end of each arm is formed into coin buckets 52, 53 and 54 respectively, each open at the top and forward side. The carriage is so balanced about the shaft that it will normally assume the position indicated in Fig. 2 with the buckets carried upwardly and the tie bar downwardly. A mercury switch 55 is fixed to the arm 49 to be rocked therewith, and from the switch, the wires 56 and 57 lead to complete an electrical circuit through an electrical motor 58 from line wires 59 and 60. The motor 58 operates a pump 61 having an intake pipe from ran underground storage tank (not shown) and ides through 'collars 25 I which may be shi ed along the tubing and supply pipe 13.

a discharge pipe 62 connected to the tankM In the discharge-pip is fitted a control valve 63 which may operated by revolving the shaft 64. A lever 65 is fixed on the shaft 64 and is normally pulled to a closed' position by the s ring 66. An operating bar 67 is supported ythe frame 12 to be moved horizontally fore'and aft by a knob 68 on the vforwardly projecting end of the bar. Aconnectin link 69 interconnects the lever 65 with the ar 67whereby pulling the bar outwardly will rock the lever 65 to open the valve 63, and release of the bar will permit inwardly from u mediately 66 to close the valve and pull yback Pins 70, 70, 70 project laterally the bar, one under each of the horlzontally disposed arms of the bell cranks 44,45 and 46. i We mount the coin selectors 71, 71, 1, imabove and in line with the coin buckets. Each selector 71 Fig. 4, consists essentially of a vertically disposed mount'- ing'plate 72 with a flanged guide 73starting the spring the bar.

u angularly downwards from the up er front corner at which point the plate is ent over slightly so that coins too small in diameter willrock over and drop laterally from the n down the guide to drop down the guide.A Goins of proper diameter roll on vertical -chute at the rear edge of the plate, at the bottom endv of whichV is -a slot 74 of a width preventing genuine coins from dropping therethrough, but permitting 'thin spurious coins to drop through. From the bottom of.

` the vertical gu1de,a forwardly sloping guide h7 5 leads with-'a trap door 76 along its under side. A coin too heavy in weight to be genuine rocks open thedoor 76 and falls thereout, whereas a ycoin of the proper weight, not'being sulliciently-heavy to swing the door open, rolls on across lto drop down into the rearwardly and downwardly directdoor 79 so ed guide 78, inwhich is. a tra ight, it willy mounted that if a-coin is too .1' roll on across the door and be discharged to i' the rear, but, if heavyenough to be genuine, will rock open the 4door and fall therese through intoa -coin bucket `immediately therebelovv.

The structure here shown, having three coin selectors, is adapted to be operated yby coins of three.- different denominations, for example, twenty-tive cents, fifty cents, and a dollar, the openings into the coin selectors and. guides thereinbeing formed proportionately. As an illustration of -the operation ofthe invention, a Idollar coin is dropped into the slot 80 over the receiving guide of the selector 71 therebehind. The coin, being genuine, passes through the selector and drops into the bucket 52. The weight of the coin in the bucket' causes the carriage to rock and, carry the bucket downwardly. within the bucket contacts the downturned The coin 'mamas of the cranks 46,45 and44, which causes the downwardly extending arms thereof to swing -toward the vertical line and uncover the front openin of the buckets therebehind. As soon as the oat21 raises the tube 22 to cause the crank 44, to be rocked, the coin may roll out of the bucket 52 down a chute 82 intoany i suitable receptacle below (not shown). As the coin leaves the bucket, the bucket is re-v lieved of its weight and rocks upwardly to cause the mercury in the switch 55 to How rearwardly and break the circuit to the motor 58, thereby stop ing the flow of iluid to the tank 10.l The deposit of a smaller coin in the proper selector 71 would have caused the' motor to have stopped sooner, since a oat 21 would have contacted a tube 23 or 24 either l of which projects into the tank to a greater distance so that the corres nding crank 45 or 46 would have been roc ed to release the coin in the bucket therebehind.

' The tank 10 havin been filled to the proper levelv for the coin eposited, and the motor 58 having out on t e bar 67, opens the valve 63, and thereby allows the fluid to leave the-tank 10 through the dischar e pi 16 and out the Ahose 83 which is pre erab y wrapped its entire length with a stili spring wire 84 to prevent sagging of the hose. As a precaution against the purchaser dropping a smaller coin into either bucket 53 or 54 while the bar 67 is held out to start the motor and cause been stopped, the purchaser pulls' more fluid to ow into the tank and out the 'then open discharge pipe 16, we provide the pins70, as arms of all the cranks 44, 45 and 46 sothat all buckets 52, 5 3 and 54 are opened and can not retain coins andetherefore, .a continued flow of fluid can not maintained following the dischargel of the measured quantity actually paid for. The arms of the cranks under which the pins 70 pass, swing downwardly since they are longer than the downturned arms of the cranks, and the normal positions of said first arms are slightly slopin downwardlyfrom a horizontal position,te pins 70 rocking the arms upwardly to horizontal ositions upon `travel forwardly thereunder. elease of the bar 67, permits the'spring 66 to return it to close the valve g3 apd allow the cranks 44, 45 and 46 to drop ac c While we have herein described and shown our invention in the one best form as now above described to pass under the' normally tend tol known to us, it is obvious that structural 5.
